Special Containment Procedures: Due to the destructive properties of SCP-1053, it is currently isolated in Area 1053. Mobile Task Force Omicron-7 ("Bounce Houses") is always on alert, stationed outside of Area 1053 in order to end Emergence events. SCP-1053 itself is encased in a steel box, with a sensitive scale below it in order to act as an early warning system for Emergence events. Purposeful testing with SCP-1053 has been discontinued, and as such, access is prohibited under normal circumstances.

Description: SCP-1053 appears to be a street map of [REDACTED], centered on the most urban portions of the city. The date on the map (as well as its features) are consistent with the year 19██. Under most circumstances, the map is mundane, excepting the mild regenerative properties it possesses (see below). The map is made out of paper, and samples have shown no anomalous properties. Unfolded, SCP-1053 is 0.25m x 0.4m, and folds to 8cm x 5cm.

Periodically,1 SCP-1053 will cause a Lamed-Gamma level spatial anomaly, known as Emergence events. Land within a 50m radius of SCP-1053 will begin to change into streets, buildings, sidewalks, and other scenery consistent with the city of [REDACTED] in 19██. Actual landmarks, street names, or neighborhoods from [REDACTED] do not exist; rather, small details (such as streetlamps, the style of buildings, etc.) are pieced together to form this new area (hereafter Ground 1053). Scenery inside of Ground 1053 has been described as "extremely urban" or "a nest of streets," and subjects have detailed the entire place as being a twist of asphalt and dirt streets, narrow roads, and tall glass buildings.

The radius of Ground 1053 expands quite slowly, although external viewing of Ground 1053 is inaccurate due to the fact that Ground 1053 is a spatial anomaly. Measurements can be taken for its external area and still be accurate. However, subjects inside of Ground 1053 have reported that it is much bigger than it appears on the outside. Calculations have placed the internal size as approximately ███% of the external size, although it is possible that the internal size is highly fluctuating, which would allow the estimation to have a margin of error as high as 15%.

The weather inside of Ground 1053 is similar to the weather outside of it, although raindrops and snowflakes do multiply as they enter the area, keeping them at normal size. Other natural forces do affect Ground 1053. However, natural phenomena such as lightning, rain, snow, and wind do not appear abnormal.

No organisms have ever been encountered inside of Ground 1053. Empty places of residence, such as apartments and condominiums, have been encountered. However, no personal belongings have been discovered inside of these residences; dressers are present but empty, walls are barren from wallpaper or pictures, etc.

After Incident 1053-01, it has been concluded that once sufficient damage is dealt to SCP-1053, Ground 1053 will immediately stop expanding. Within less than 30% of the time it took for Ground 1053 to be created, the entire area will fully disintegrate. During retrieval time, SCP-1053 usually is fully repaired by unknown means. The state of SCP-1053 before the expansion of Ground 1053 has no effect on the growth; rather, the difference of the condition of SCP-1053 before Ground 1053 is generated is directly proportional to the amount of damage that must be dealt to SCP-1053 for Ground 1053 to disintegrate. It is speculated that if SCP-1053 were to sustain enough damage prior to the generation of Ground 1053, stopping it from expanding would become impossible, causing a CK-end-of-world scenario.

MTF Omicron-7 ("Bounce Houses") is tasked with entering Ground 1053 during Emergence events. Rapid response is key in ending Emergence events, as the longer Ground 1053 has to expand, the area needed to be covered in order to reach SCP-1053 will increase exponentially. In addition, technological capabilities inside of Ground 1053 have been greatly inhibited, for unknown reasons. To date (██/██/20██), the farthest that Ground 1053 has reached externally is ██ kilometers.

1. Thanks to research by Dr. ██████, the Foundation has concluded that Emergence events occur when the nation of [REDACTED] nets approximately █0,000 new inhabitants. Efforts are currently being taken to keep [REDACTED] stagnant.
